这间低屋顶的房间通风不好，令人气闷。

[误] The air in this low-ceilinged room was stuffy and oppressive.

[正] This low-ceilinged room was stuffy and oppressive.

注：虽然汉语中可以说“空气闷”，但是在英语中，stuffy 和oppressive 等的主语不能是air，而应当是某个地方，如theatre（戏院），classrooom（教室）等名词。

stuffy: 通风不良的;窒息的;闷热的
a stuffy room
空气不流通的房间

oppressive: 压抑的;沉重的;烦闷的
